Efficiency Improvements for Internal Combustion Engines

[dcb]

They have 2.5 million to make it work, and come up with some usable data, why don't we talk about it then?

You do realize that the "22.7%" in my signature represents a fuel economy improvement, right? Even when I do city-only driving in my truck, I still get around 7% better fuel economy over what this 4400+ lb beast I drive is rated for.

Almost all of that is due to engine improvements, and those engine improvements I have done are of the garden-variety nature. I do not get the luxury of practicing hypermiling techniques due to the nature of the traffic I encounter in my commute. My version 2 aerocap hasn't even been fabricated yet, so there's no contribution there.

Clearly, if I can squeeze a 22% fuel economy improvement out of a 4.7L V8 engine using commonly found techniques, there's still more that can be squeezed out of the existing internal combustion engine.

The allure of that is, new readers looking for improvements to their own engines won't be sidetracked by wave motion engines out of Star Blazers, or thermodynamically dubious contraptions that have been developed for 10+ years and have yet to be introduced into the mass market.
